Same issue, 2/6/2022 even after the February update.
Verizon pixel 6 pro using a macbook pro and imac both updated to v12.2 and chrome v98.0.4758.80.

Fastbootd (not fastboot) I can at least get it to download but it won't install. Pretty sure the website for this is the issue, when it checks the state your device is in, it's looking for the wrong state or something.

Now would be a great time to chime in Google support/techs.

In console I can see "compiled_en.js:1767 Fastboot command (oem udfps get-cal-url) failed: 'Unknown OEM command'" but I have no idea what this means.  I'd presume the code to do the install is bad.

Same problem here. Pixel 6 with replaced, but original display, now fingerprint sensor isn't enlisted. This error message comes up when trying to add fingerprints for screen unlock using fingerprints (German: Einstellungen->Sicherheit->Entsperrung per Fingerabdruck -> Mehr -> Mehr -> Ich stimme zu->Starten--> Error Message "Registrierung wurde nicht abgeschlossen - Fingerabrucksensor kann nicht verwendet werden...")

I tried:
1) Factory reset ->Same error message as above
2) https://pixelrepair.withgoogle.com/udfps on Chromium/Linux and Chrome/Windows
After starting the Pixel 6 in fastboot mode and connecting to the computer, at the step "Downloading", I get the error message
                                       -> "Couldn't find the unique calibration software for this device"

I'm having the same problem after a screen replacement
Tried:
Factory resetting multiple times
Enrolled in Beta testing - failed
Flashed with android flashtool https://flash.android.com/ 

Cannot get the fingerprint calibration to work!

Same problem since an authorised repair in November 2021

Same problem Couldn't find the unique calibration software for this device Pixel 6 Pro

Same Problem had my screen repaced yesterday and cannot get my fingerprint scanner working

Same issue here. I tried the factory reset via the phone's software and that did not help.   I tried downloading the calibration software from 6 different computers including Win 10, Win 11, and Chromebooks.  Same error message every time.

I've tried different USB c cables , multiple operating systems and versions such as windows 10 , windows 7 , Linux Ubuntu .

With my pixel 6 pro , I have been on the latest February 5 patch, now. Currently running beta version 3 12l

Everything I try results in the same error!

Please google explain what's going on here , we just want to get back to enjoying our phones and it's hard to do that with out biometrics.

Google please respond .

Thank you .

Same Issue.

Tried the calibration in windows 10, windows 11, ubuntu, chromium, mac and with another pixel 3AXL.
Tried uninstalling and reinstalling USB drivers, with android studio installed.
Tried resetting the device 3 times with every new patch google released.
Tried re-flashing the October image and then again after updating.

Bought the display from https://www.aliexpress.com/item/1005003553710431.html?spm=a2g0o.9042311.0.0.30944c4d4zdBD4

Hello! I'm from Russia. I broke the screen on my pixel 6 pro, the master replaced the display, the fingerprint sensor disappeared from the sewing. After some attempts, he appeared, and then disappeared again. Didn't find it again. https://pixelrepair.withgoogle.com/ does not find it, gives an error. Help with advice on how to make it work? I'm very sad.

Same problem, pixel 6 pro

I have the same problem, this is such a pain.  So many accounts for airlines, insurance, finance, car rental, etc... and I now have to remember user IDs and passwords to get in.  This typically means resets.

GOOGLE get this issue fixed for Pixel 6 pro.  Love the 2 sims, but a broken and replace glass should NOT cause this much trouble!!!!

I had my Google Pixel 6 Pro screen replaced. The repair shop couldn't get the fingerprint reader to work with the new screen, however I should be able to recalibrate the fingerprint reader by going to https://pixelrepair.withgoogle.com/carrier_selection and selecting "Install fingerprint calibration software" which redirects me to https://pixelrepair.withgoogle.com/udfps

When following the instructions and connecting my phone to either Windows 10 or Chrome OS I get an error during the "Downloading software" step stating "Couldn't find the unique calibration software for this device"

Same issue.

Same issue, reported in numerous threads.  Please, for the love of god, get your sh$t together Google.  I love you, but we may have to break up!

I did some debugging in the Fingerprint calibration tool using developer tools.

During the first step for the installation, the page attempts to download a file using a GET command using the following path.
https://storage.googleapis.com/hardware-mfg-data-ext-sacal/a41e001f3706fe.signed.cal
If it fails with a 404 error (file does not exist), it tries again using uppercase letters and gets the same error.  This is easily visible in the network tab.
The JavaScript looks for errors during download.  If it gets a 404 error it always displays the message "Couldn't find the unique calibration software for this device"

I wasn't able to figure out where a41e001f3706fe is coming from.  Perhaps it's an encoded OS version number.  It will never work until that file exists.  I'm thinking if the OS is downgraded on the phone to an older version (perhaps the first version that was released with the Pixel 6) it might change the file it's looking for to something that does exist.

Google ? Any updates? Please don't leave us in the dark any longer

same this is really annoying that we can't fix the screen

Yep - same here. Devs... let me know when you have a solution and I can beta test for you.

Same issue here. Have gone to a google repair center, they installed a genuine screen with fingerprint sensor attached, and when we run the google recalibration software, I get an error message saying that it "couldn't find the calibration software for this device". Phone is 8 weeks old (Pixel 6 pro) and already it's lacking the fingerprint scanner. Not cool.

Dear Google,

Don't miss comment #20 from March 7th -- it gives a very plausible explanation for the problem, and thus a probable easy fix.

https://issuetracker.google.com/issues/218761008#comment20

Still the same issue happening on March update. Please for the love of god fix this issue so I can use the fingerprint scanner, Google!

I got mine fixed. Apparently its an issue with the screen.

ubreakifix said there are faulty screen units that doesn't recognize the tool.

You just need to go back where you get your screen replaced and ask to order another part.

So official Google repair has ben using fault screen units.  Why does this not surprise me?

Also experiencing the same as other users.

First return to Pixel since Nexus and not a good sign already with this.

have the same problem

Looking at the network traffic when running it, it is making a request that is 404ing. So would be great if Google could provide any updates on this.

I can't see how different browsers and OS will make any difference to a file missing on the server

I've tried multiple computers Windows 10, 11 Mac no luck. This is really average from one of the biggest tech companies on Earth.

Same issue. Friends have asked me about this exact issue and due to my feedback, will not be getting the latest google.

+1, my pixel 6 had the screen replaced and now I don't have fingerprint scanning

I've managed to transfer original fingerprint sensor from old screen, - phone is recognizing finger, almost goes full enrollment setup but at last step gives error "Enrollment was not complete. Try again or use a different finger" Tried updating to latest, did factory reset, still same error...

Tried calibration tool and it fails as it's explained here... Several months have passed and google is silent about this.. I'm gonna sell this phone and never look back. Every Pixel phone I owned had some kind of unique defect that I didn't have on any other brand phones... This is hilarious

 same issue happened to me . Please fix this issue

Same issue here, replaced screen with genuine screen from another phone and the software downloader doesn't work

Same issue here. WTF Google

No monitor replacement but fingerprint sensor is not working.
Try to use the tool to fix it but fail to find the unique software.

Same issue. Tried different cable, computers and drivers. No luck.

Same issue here,

Same for me as well.

same issue

also same issue :(

same issue, tried different host devices, issue persists

I've tried both windows and mac, getting the same 404 error on the .cal download. Seems like it's as simple as changing a url? Not sure how this issue has been sitting for 3 months

Having the same issue

Same: Couldn't find the unique calibration software for this device

404: No such object: hardware-mfg-data-ext-sacal/a5011431021c3f.signed.cal

May 27th, Same issue with my Pixel 6 Pro. I am being told by the repair facility that it is because I am running beta android 13 software, but considering people here have done many resets and such, I am of the mind that it is not the fault of the device, but something on Google's side.

I reached out to Google and have had ongoing communication with them about this issue and they offered the same "Hope the June update fixes it" nonsense. I pushed back multiple times, using this and multiple other posts and sources as citation for the problem. Showing them comment #20 directly as well. Frankly for a multibillion dollar software company, "wait and see" is just a ridiculous reply but that is always their reply.  They won't budge on a fix, they won't even offer a timeframe or ponder where the issue even lies. Pure insanity. I gave them this as a reply.

Myself to Google:
"This has been a known issue on your end since November of 2021 (Information Here), how it hasn't been fixed by now or at the least have a timeline for repair that can be relayed to customers beyond "hope the next update addresses it".  What kind of solution is that? There is documentation of it on a Google site as well (Here) and the issue appears to be that the file to calibrate my screens fingerprint sensor does not exist on your server (Proof also see attachment)

So the community has done the work for you, fixing the issue should not be guess work.
This is my 4th phone, I am frankly beyond tolerating guess work and "hope" so my accepted solutions are as followed in order of most preferred to least prefered:
1. Fix the issue that is causing this so I can calibrate the phone I have currently that *was* working fine.
2. Refund the cost of the device.
3. Replace the device with a BRAND NEW hardware kit in advance of my returning of the defective hardware. If this new device must be sent to a partner like UbreakIFix to accomplish said advance return, that is acceptable."

This was their response in its entirety:
"Hi XX

Thank you for contacting Google.

We understand your frustration about this concern. The option that we have is replacement or refund please choose which one would you like to use so that I can process your request.

I hope you understand.

We look forward to hearing from you."

So they completely opted out of anything to do with fixing the device I have in my hand which is my absolute preferred option. This is just sad honestly.  I have owned every mainline Pixel since the 2xl, I am typing this from my Pixelbook while listening to music via my Pixel Buds. I have thousands in Google products, I have convinced my brother and mother to buy Pixel phones (5a and 4a respectively) and as a customer I feel incredibly let down. I knew this device would be more trouble than my 2xl, 3xl, or 4xl, I was aware it's Google's first inhouse chip and the issues that come with that. But 4 phones later, I'm done. My first 3 had terrible overheating issues that destroyed the battery life in hours, as well as the awful connectivity issues that caused it to disconnect all of the time. I finally get a great functioning device, and the screen goes funny, I go to a Google partner to deal with the issue and now I have a phone missing a feature that is vital to every day use, and a company basically telling me "sorry bro." Crazy.  At this point I really don't even want another Pixel, or Android device in general and I never expected to feel that way.  I fully expect I won't have a functional Pixel 6 until the Pixel 7 launches at this point.

Google, get it together or I will be using the refund you offered to unfortunately justify a change in ecosystem. I strongly recommend others having this issue opt for a refund as well. Maybe if enough people hit them in the wallet, this will resolve.

Same problem here. Tried all different builds, full wipes, repair tools etc. This happened after a screen repair.

Just installed Android 13 Beta 3 and it does not work for me...
Still 404 "No such object: hardware-mfg-data-ext-sacal/a6180b1b1f1281.signed.cal" error when trying to download the tool on the phone.

Still not working with Android 13 beta 3 unable to find unique software

Still not working, when the hell is Google actually going to fix this issue? This is ridiculous, especially for their flagship phone.

Still not working

Pixel 6 here. Screen replaced in Sydney by authorised repairer. Same issue. Cannot 'enroll' ... setting up fingerprint scanner. Cannot use the update and software repair as per all the comments above i.e. in the download phase the error message, 'Couldn't find the unique calibration software for this device'.

Flagship phone. Common problem. No help.

Agree with  #20, I also tracked with network debug in chrome. The version of the file my browser tried to fetch was different version than #20 reported. I'm on Android 12 still.
https://storage.googleapis.com/hardware-mfg-data-ext-sacal/A501021D0F0916.signed.cal
Browser tried for the file with uppercase and lowercase letters.

I would assume that when new version of android are built, they're either not building this software package, or they're not delivering the artifact it to the Google Cloud Storage Bucket.

Should we try downgrading software to the ota?

Already tried with the first October 2021 build for the Pixel 6 and also the latest Android 13 Beta. The same file is requested and the same 404 error is given.

Same

I still don't understand how they haven't addressed this with their flagship phone.

Also having this issue

Same as everyone else.

July 19th ... just purchased pixel 6, dropped it, repaired screen and here we are: same problem as everyone else even after all of this time not addressed by Google.  INCREDIBLE! This is my first time buying a pixel and it will be my ONLY time ever buying a pixel. Never again buying any Google device.

I've already moved back to Samsung

Repaired the screen on my pixel, finger print calibration doesn't work "Couldn't find the unique calibration software for this device"
what does this mean?

Fingerprint repair tool doesn't even connect to my phone in fastboot mode. Says "unable to connect". I have all the drivers installed, and the tool can recognize my phone when I try to do the full software update in rescue mode. But I still cannot run the software update because it says the firmware on my phone is newer than the firmware on the tool. Seriously google, wtf

"Unable to connect to the Phone" Tried on 3 different windows machines. Installed the proper drivers. tried two different screens, and 3 different sensors. This "tool" doesn't work. Very disappointed.

SAME SAME SAME.  How ridiculous Google.  I am getting the same message as #75.  

I had my screen replaced again , this time through a different phone repair place that I new provide genuine screens , and now the calibration software worked .

So it's either non genuine, or screens provided for another region and it won't work I was told .

Yes .. I've broke my screen twice first replacement I ordered from place in
Sydney , the calibration never worked, months later this display dropped
working, this time I ordered  display from very reputable company in Sydney
who 100% claimed genuine displays..
This time the calibration worked ..

So it's definitely not genuine displays, I was also told it can be that the
display is genuine but is for a different region of devices

So I just got my screen replaced on my pixel 6 today by myself and was so excited to get back my phone. Everything works but the fingerprint.

The fingerprint calibration is such a headache because it's supposed to be a 1 2 3 easy steps but there's some extra steps you need to do.

This is how I made it to work:

1.Before you turn your phone off, go to the developer options and enable USB debugging.

2. Go here Get the Google USB Driver  |  Android Developers and download the google USB zip file (this is for windows BTW)

3. Unzip however you want it

4. Open the folder usb_Driver and rightclick "android_winusb" and install

5. To make sure it installed, connect your pixel (with USB debugging still enabled) to your PC and open "device manager". You should see "Android Devices > Android Composite ADB Interface".

6. Disconnect pixel from PC

7. Go here Google Fingerprint Calibration website and follow the instructions.

SHOULD WORK!

Good luck!

Same issue screen replaced, "Could not find the unique calibration software for this device" when trying to download calibration software

Same here. Screen replaced (original part), fingerprint gone. Enrollment incomplete and calibration tool keeps saying that my Pixel 6 version is newer than the one tool has. Ridiculous.

exact same issue here, screen replaced and followed all the steps and still getting the "Couldn't find the unique calibration software for this device"

Any fix yet?

Well, Google has done the impossible!  I, too, have had my Pixel 6 Pro screen replaced and lost the use of the fingerprint sensor.  Google has known about the "Couldn't find the unique calibration software for this device" issue for a year, and has done nothing.

So what is the impossible thing Google has done?  I will be buying my first Apple product ever: an iPhone!!!!!

Hi there,
I had the same issue after an authorized screen replacement on my Pixel 6A phone.
I have followed instructions from message #81 and I've fully recovered the function so many thanks!!
